Stanley, an 80-year-old man is having his annual checkup. The
doctor asks him how he's feeling.

"I've never been better," he replies. "I've got a twenty-two-
year-old bride who's pregnant with my child! What do you think
about that?"

The doctor considers this for a moment, then says, "Well, let
me tell you a story. I know a guy who's an avid hunter. He
never misses a season. But, one day he's in a bit of a hurry
and he accidentally grabs his umbrella instead of his gun. So
he's walking in the woods near a creek and suddenly spots a
beaver in some brush in front of him? He raises up his
umbrella, points it at the beaver and squeezes the handle...

*BAM* The beaver drops dead in front of him."

"That's impossible!" said the old man in disbelief, "Someone
else must have shot that beaver."
